Abstract :
In this paper, we propose a robustness measure for LTI systems with causal, nonlinear diagonal perturbations with finite L2-gain. We propose an algorithm to reliably compute this quantity. We show how to find a state-feedback controller that achieves the global maximum of the robustness measure.
